PIPE-PAINTING MACHINE.

Specification of Letters Patent.

Patented 1a.. 15, 1921.

Application filed March 25, 1920. Serial No. 368,487.:

T 0 all coho m it may concern:

Be it known that I, CHARLIE A. MoN-ULTY, a citizen of the United States, residing at Powderly, in the county of Lamar and State of Texas, have invented certain new and useful Improvements in Pipe-Painting Machines, of which the following .is a specifica- This invention relates to improvements in devices for painting pipes or other elongated substantially cylindrical objects.

The principal object of the invention is to provide a device for painting pipes which will accomplish its purpose as thoroughly and efliciently as the hand and much niore expeditio usly, thus effecting a great saving in time and labor.

Another object of the invention is to provide means for salvaging surplus paint so that a minimum waste will take place when operating the device.

For the purpose of illustrating this invention there is shown in the accompanying drawings one form thereof which is at present preferred, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

In the drawings:

Figure l is a sectional side elevation of the device showing to advantage the operation of the brushes upon a section of pipe.

Fig. 2 is asectional end elevation of the cleaning apparatus. 3

Fig. 3 is a' detail view of the operating mechanism therefor, for drawing the device over the pipe to be painted.

Like characters of reference indicatedike or similar parts throughout the several views of the drawings in which: 7

A designates the cylindrical body portion of the painting apparatus which is formed of upper and lower complementary sections 1 and 2 having flanged edges. 3 through which extend bolts 4 for securing the sections together about a pipe or other cylindrical object to be painted. V

Tappedintothe upper section 1 of the body is a paint receiving funnel B which has mounted thereon intermediate its extremities a trough 5 for receiving fuel, as the paint can be applied more efl'ectively when warmed. The hand grip 6 on the funnel is guarded by a projection 7 so that the flames from the trough will not contact with the hands, of an operator. In connection with the heating apparatus it is pointed out that a very small flame is employed for the purpose and very little fuel.

Mounted through the medium of rivets 8 in each section of the body are a plurality of semi-circular complementary ribs 9 carrying bristles 10 which engage the pipe to be painted, and two pairs of the ribs are arranged in front of the entrance of the funnel 13 therein and preferably three or more pairs to the rear thereof.

Arranged below the body is an elongated a driven cog 17 on a shaft 19 journaled intermediate the extremities of the legs 13. A drum 20 is also fixed to the shaft 19 about which is wound a cable 21 the free endof which is attached to a'removable collar 22 secured to the pipe to be painted. An operating handle 23 is keyed to the end of the shaft 15 and the legs 13 and 14 are secured to the body as illustrated, so that upon attaching the collar 22 to the pipe to be paints ed the drive cog 16 is actuated by turning the handle 23 so that the cable 21 is wound upon the drum 20 and the painting device is drawn along the pipe. In operation the paint is poured into the funnel and is warmed by the heat from the fuel in trough 5 and the operator supports the apparatus in position by grasping the hand grip 6.

In order to positively maintain the device.

'of the entrance of the funnel B therein a face of the pipe is acted upon and the bristles operate to eifectively distribute the paint equally upon all surfaces or portions of the pipe.

The paint as applied from the funnel is distributed over the surface of the pipe by the operation of the rearwardly disposed brushes, and any surplus paint is effectively taken care-of by the tank which receives all such paint which is not used. Furthermore it is pointed out that when it is desired to eiiect the operation more expeditiously tWo men may be employed, one to operate the device. and the other to pour the paint within the funnel. The device is also as applicable to painting poles or other elongated cylindrical objects as it is pipes, and it is pointed out that the joints of the pipe may be painted as well as the body portion.

From the foregoing description taken 1n connection with the accompanying drawings it is thought. that a clear and comprehensive understanding of the construction, operation and advantages of the invention may be had, but while I have shown and described the device as embodying a specific structure, I desire it to be understood that such changes may be made in said struc ture, as do not depart from the spirit and scope of the invention as claimed.

What I claim is: 1.. A painting device comprising a cylindri'cal member formed in complementary sections for loosely embracing a pipe, a

. funnel tapped into the cylindrical member for delivering paint upon a pipe, means for supporting the cylindrical member upon a pipe, brushes carried by the cylindrical member for distributing paint over the pipe, means carried by said member for receiving and retaining surplus paint, and means for moving the cylindrical member over the pipe to be painted.

2. A painting device comprising a cylindrical member for loosely embracing a pipe, means carried by the cylindrical member for delivering paint upon a pipe, means carried by the cylindrical member for distributing the paint over the surface of the pipe, and an elongated tank connected with the cylindrical member for receiving and retaining surplus paint.

3..llhe combination with a painting device including a cylindrical body for loosely embracing a pipe, of means for moving the painting device along a pipe to be painted comprising a pair of supporting legs mounted on said body, a drum rotatably mounted between said legs, a 'cog operatively connected with the drum, a cable carried by the drum and adapted to be attached to the pipe, and a handle associated with the cog for rotating the same to wind the cable on the drum and draw the painting device over the pipe to be painted.

In testimony whereof I afiix my signature hereto.

CHARLIE A. McNULTY.
